. Bulbs may become very hot while
illuminated. Before replacing
bulbs, turn off the lights and wait
until the bulbs cool down. Other-
wise, there is a risk of sustaining
a burn injury.
. For models with HID low beam
headlights, observe the following
precautions. Not doing so carries
the risk of an electric shock that
could result in serious injury
because the HID bulbs use an
extremely high voltage. – Do not replace any headlight
bulbs (both low beam and
high beam) by yourself.
– Do not remove/restore the
headlight assemblies by your-self.
– Do not remove any headlight-
assembly components byyourself.
For replacement, contact your SUBARU dealer. Specifications
